JEREMIAH MCGREVY, 0F BROOKLYN, NEW YORK, ASSIGNOR TO SOLIDARITY WATCHCASE CO., OF BROOKLYN, NEW YORK, A CORPORATION OF NEW YORK.

WATCH-PENDANT.

Application filed December 27, 1909.

To aZZ whom t may concern:

Be it known that I, JEREMIAH McGREvY, a citizen of the United States,residing at Brooklyn, in the county of Kings and State of New York, haveinvented certain new and useful Improvements in fateli-Pendants; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention is an improvement in swivel pendants for time pieces, whichis particularly useful in ladies watches, enabling the wearer at will toswivel the piece about, so as to observe the time, without detaching thewatch from her dress.

Swivel pendants have been used heretofore, but they were insecurelyattached to the time piece, so that the watch was liable to becomedetached and lost. My pendant, on the contrary, is permanently andinseparably connected to the watch, by means of annular grooves in thefixed post, and a swivel member, having spun, squeezed or otherwiseformed, internal beads forced into said annular grooves.

My structure,comprising the swiveling of the movable member onto thefixed post by annular grooves and beads, results in the additionaladvantage that a short xed post may be employed, and a long swivelmember extending up above the post. Hence I can mount the sleeve for thewinding stem upon the swivel member, instead of on the fixed post.Therefore, standard sized material may be employed in my pendant, whichwas impossible in prior swivel pendants, because heretofore the stem ofthe lixed post extended all the way up through and was spun over the topof the swivel member, to prevent detachment of the swivel member fromthe watch. Accordingly, the sleeve for the winding stem had to be madesmall enough to t inside of the fixed post; with the result that allparts of the material, and particularly the winding stem, had to be mademuch smaller than standard size, and in fact so small, in a ladys watch,as to be liable to become broken in assembling or by the mere winding orsetting of the watch. I believe it to be new to fasten the winding andsetting material upon the large, outer, swivel member, instead of on thesmall, inner, fixed post.

Specification of Letters Patent.

Patented Oct. 31, 1911.

Serial No. 535,133.

In the accompanying drawing: Figure 1 is a side elevation of thestationary post. Fig. 2 is a side elevation of the blank for the swivelmember, previous to the formation of the annular retaining beads, butwith the boat in place on the blank. Fig. 3 shows the blank for theswivel member assembled over the fixed post, ready to have the beadsspun into the grooves in the post. Fig. 4 is a view similar to Fig. 3,excepting that the annular beads have been formed in the swivel member.Fig. 5 is an enlarged vertical section through a complete pendantembodying the invention. Fig. 6 is a side view of a complete pendantarranged in position.

Referring particularly to Figs. 1 and 5, the stationary post 2 is formedwith an oval base 4 for attachment to the watch case 1; also with aprojecting cylindrical sleeve 11 and with one or more annular grooves 5,6, above the base 4. As shown, the annular ridge 9 separates grooves 5and 6. The sleeve 11 is tubular, to permit of the passage therethroughof the material which comprises winding stem 12 and sleeve 13.

Referring to Fig. 2, the blank 10, of swiveling member 3, has mountedthereon, as usual, the boat 15 prepared to receive the bow 16.` Theswiveling member is a straight cylindrical blank, and is bored out justright size to accurately it upon or telescope over the cylindricalsleeve 11 (as illustrated in Fig. 5).

In Fig. 3, the blank 10 is shown slid or telescoped upon the cylindricalsleeve 11 and over the annular grooves 5 and 6, and the annular ridge 9of the stationary post 2, being slid down until arrested by the ovalbase 4. With the parts in this position, the lower end of the blank 10is spun or otherwise squeezed into the annular grooves 5, 6, in the base4, thereby forming beads, or interior ridges 7 and 8, corresponding toand accurately fitting within the annular grooves 5 and 6 in the post 2,as is clearly shown in Fig. 4, and in sectional view in Fig. 5.

The upper end of swiveling member 3, extends up considerably above thetop of sleeve 11, and is threaded at the top to have screwed thereinsleeve 13 of winding stem 12, all as clearly shown in Fig. 5. When thepost 2 and swiveling member 3 have been thus assembled and permanentlyand inseparably connected together by means of the annular grooves 5, 6,and the annular beads 7, 8, the post 2 is next brazed to the watch casel, in the usual manner; then the sleeve 13 is screwed into its place inthe upper end of the swiveling member 3, with the winding pin 12 in itsplace in the sleeve, the crown 14 is screwed onto the upper end of thewinding pin, and the bow 16 is inserted upon the boat 15.

I do not intend to limit myself to the precise construction shown, norto the use of a plurality of annular grooves 5, 6, and annular beads 7,8, since the purposes of my invention may be eifected with only a singlegroove and bead; and I do not intend to limit the part ofl my inventionwhich relates to mounting the material upon the swiveling member, to theuse therewith oi the annular grooves and beads shown, but wish it to beunderstood that, so far as this part of the invention is concerned, itis immaterial by what means the swiveling member is mounted to swivelupon and be attached to the fixed post. The gist of this part of theinvention is that the material be mounted upon the exterior piece,namely, the swiveling member, instead of to the ixed interior post,whereby a larger sized material can be used than would be possible if itwere mounted within the interior piece.

Having thus described my invention, what I claim and desire to secure byLetters Patent, is

1. A pendant formed with a part integral with the casing and comprisinga stem with an annular groove, and a swivel member telescoped thereonand having a reduced annular bead spun over said groove on the stem, topermanently and inseparably connect said members together, whilepermitting the one member to swivel on the other.

2. A pendant formed with a part integral with the casing, and having agrooved stem, and a swivel member having a bead fitted into said groovedstem, so as to permanently and inseparably connect said memberstogether, while permitting the one member to swivel on the other.

3. In a swivel pendant, in combination with the winding material, ahollow post rigidly secured to the casing and having a grooved stem, aswiveling member having a bead fitted into said groove, so as topermanently and inseparably connect said members together whilepermitting the one to swivel on the other, and means for attaching saidwinding material to the swiveling member.

4. In a swivel pendant, in combination with the winding material, ahollow post rigidly secured to the casing and having a grooved stem, aswiveling member having a bead fitted into said groove, so as topermanently and inseparably connect said members together whilepermitting the one to swivel on the other, said swiveling memberextending up beyond t-he post, and means for attaching said windingmaterial to the swiveling member.

In testimony whereof I aiiix my signature in presence of two witnesses.
